If you’re planning a trip to Thailand, don’t forget to complete the Thailand Destination Arrival Card (TDAC) before you go. All non-Thai nationals must submit this form online within 3 days before arriving in Thailand.
You can fill it out here: tdac.immigration.go.th. There’s no fee, so be sure to use the official link above and avoid unofficial websites that may try to charge you.
It only takes a few minutes—and saves you a hassle at the airport. Safe travels!
